title: Analysis of Bacillus subtilis tagAB and tagDEF expression during phosphate starvation identifies a repressor role for PhoP-P.
abstract: The tagAB and tagDEF operons, which are adjacent and divergently transcribed, encode genes responsible for cell wall teichoic acid synthesis in Bacillus subtilis. The Bacillus data presented here suggest that PhoP and PhoR are required for direct repression of transcription of the two operons under phosphate starvation conditions but have no regulatory role under phosphate-replete conditions. These data identify for the first time that PhoP-P has a negative role in Pho regulon gene regulation.
